Replacing Lower c pillars or just weld patch

Afternoon all,

I am getting ready to replace both sills to galv and I and trying to decide what to do on c pillar

Last night I removed body section to get a better look at pillars .As you can see below is it the last few inches where rust has taken hold

I like the idea of replacing everything with Galv that I can while I am at it. The b pillars are sound and in good shape as well as bulkhead.

I assume that you have to take the entire c pillar out to separate the lower angled section from the top. I saw a tutorial on replacing bottom section on Yrm on doing this.

How difficult is this and is it just the spot welds to the sill and the rivets as well as bolts holding the entire c pillar on the truck. I would rather replace lower section than trying to patch honestly ...

I saw where Doug recommended to pull the entire t section out and weld ( I donít have that much confidence in my skills at this point)

I figure I would build a templet to match to existing angles and use with new metal sections and then remove sill and replace with new galv sill. Remove c pillar separate and rebuild using templet. And spot weld c pillar and to sill locations.

Any pointers .. getting ready to purchase Yrm galv materials

Thanks

c pilar is part of the sill- its all one piece from the bulkhead back. You have no choice but to dive in man

So you are saying B needs to come out as well

I thought I could remove spot welds save the tabs and re-weld

The whole thing needs to come out. You can cut, clean and weld in place too but you won't be able to do as clean of a job as you would by removing it. Check the sill rails, they ight be on their way out as well.
I did it on my truck, but mine were in a much worse shape than yours (https://www.defendersource.com/forum...tml#post777831).

You will reuse the tabs on the B-post. The back flap will give you trouble, though, very hard to remove those spot welds from behind, again, I know, because that's what I did - I removed one of the sill rails while keeping B-posts attached. I didn't bother for the second one - removed the whole panel first. I tacked everything back in place, and then still removed the entire panel off for final welding. Make sure you template everything before you start dismantling.

Unless you're good with a welder/grinder and are doing the work yourself, I'd recommend just getting complete HDG replacement pieces. There was a recent discussion about this topic here in the last couple of weeks, and RN seemed to have a deal on the whole panels. Patching it will just prolong the agony.

Just spoke with local defender owner here and explained what yíall are saying.. I am a little slow at times....

So is the Yrm 3 piece kit good?

Mike (local owner) suggested The process would pull the entire side frame support the roof - use as templet for new 3 piece kit and have welder rebuild then have it galvanized .... RN at 1800 is crazy $$

I guess I could rebuild/ galv my existing pillars using newly build kit as templet and save for next build donít tell wife ...

One sill is bad the other isnít that bad and prob could be repaired

Thanks all for spending my $$

Thanks mike for call ...

We repair and galv them regularly. If you check UK prices RN is right in line on Genuine. I havent seen the new YRM erector set yet but these control how your truck fits togecther. I would definitely not disconnect the b pilar from the sill, my .02

Hopefully when Miket961 helps me remove the whole panel(s) I can get it repaired and save some $$ !!

For now I am going to cut off the lip so I can get the sill thresholds on ...

cut the p shaped metal lip off, drill out the rivets for the rubber seals on the sills if they are even still there, and use the tdci type lower door seals when you go back together
